[PATCH 0/5] Add glob pattern matching support on trigger and kprobe-event
Hi, Here is a series of ftrace/perf updates to support multiple event select operation by glob-based wild cards. I've ported strglobmatch from perf-tools (with recursive call limitation) for this use. It is easier to use (just replacing strcmp) but ...

[RFC/PATCH 1/2] perf script: Add --time-filter option
From: Namhyung Kim <namhyung.kim@lge.com> The --time-filter option is for limiting samples within a range of time. A time range looks like <time1>-<time2> and at most one of them can be omitted. For instance: $ perf script ...

[PATCHSET 00/15] perf tools: Introduce new 'ftrace' command (v2)
Hi all, This patchset implements a front-end tool for kernel's ftrace. It uses function_graph tracer by default and normal function tracer is also supported. (Of course you need to enable those tracers in your kernel first.) NOTE: It's in very ...

[PATCHSET 0/9] perf tools: Assorted fixes and changes on perf top/report
Hi, This patchset is a collection of 3 changes on perf top and report tools. I wanted to make them independent, but failed due to laziness. :) Patch 1 is a fix for -E option handling in perf top. IIUC it only shows a given number of entries. ...

[PATCH 1/2] perf report: Add --percent-limit option
From: Namhyung Kim <namhyung.kim@lge.com> The --percent-limit option is for not showing small overheaded entries in the output. Maybe we want to set a certain default value like 0.1. Cc: Andi Kleen <andi@firstfloor.org> Signed-off-by: ...

[PATCH 1/3] perf top: Get rid of *_threaded() functions
From: Namhyung Kim <namhyung.kim@lge.com> Those _threaded() functions are needed to make hist tree handling thread-safe, but AFAICS the only thing it does is forcing it to use the intermediate 'collapsed' tree. It can be acheived by setting ...

From: Namhyung Kim <namhyung.kim@lge.com> The -E/--entries option controls how many lines to be printed on stdio output but it doesn't work as it should be: If -E option is specified, print that many lines regardless of current window size, ...

Linux 3-10-rc1
So this is the biggest -rc1 in the last several years (perhaps ever) at least as far as counting commits go, even if not necessarily in actual lines (I didn't check the statistics on that). Which was unexpected, because while linux-next was fairly ...
